摘 要
当前我国设计的井盖监测主要通过在井盖上放置标识等放置被盗，然后监测到被盗后，通过摄像头对其进行跟踪，导致当前还是存在很多井盖被盗，因此此次设计一款主要针对井盖防盗系统，监测到井盖移动时发送信息到管理人员的手机上，此外此次设计还增加了温度检测、水位监测和甲烷监测，使得井盖更加的安全。
此次设计采用硬件和软件配合进行设计，硬件采用STM32单片机作为主控芯片，采用霍尔传感器对当前井盖是否移动进行监测，采用DS18B20对当前的温度进行实时监测，采用超声波对当前的水位进行实时监测，采用甲烷监测模块对当前的甲烷浓度进行监测。然后通过keil5对程序的编程，进行主程序、数据采集功能子程序、按键子程序、显示子程序、WIFI通信子程序进行撰写和调试，然后通过软件和硬件的配合进行调试，此次设计最终调试可以实现井盖的情况和井盖环境进行实时监测和数据的实时传输。该控制方案更加科学合理,性能稳定,功能完善,成本低廉,实际效果理想.

Abstract
The thermoregulation function of infants is not perfect. One of the most important measures for effective nursing of infants, especially infants with very low body weight, is to maintain an optimal environment. A large amount of modern biomedical data shows that a warm environment can reduce the incidence and mortality of infants caused by direct or indirect cold stress response, thus effectively guaranteeing the survival rate of newborns. The crib can create a comfortable environment with clean air and suitable temperature and humidity for the newborn, so as to avoid the infection of the baby to enhance its body resistance and ensure the growth of the baby. Traditional cribs have the following drawbacks: family members listen to crying before calming down, lack of crying detection; Lack of bed-wetting monitoring; ; Can not realize automatic temperature and humidity control; The crib cannot be tested for impact.
In view of the traditional control equipment of the poor ability of automatic control is improved, the baby bed temperature and humidity control system as the carrier to complete the data acquisition and signal processing, core USES STM32 MCU, and comply with, drive heating, cooling, humidification, dehumidification, music playback, shaking table for processing, with liquid crystal display module as a display unit, complete the temperature and humidity, the baby is No crying detection module, whether the baby is bed-wetting detection module, whether the baby is hit detection module and other signals are sampled to realize the monitoring of the designed crib.
The monitoring system is an improvement on the traditional crib in both hardware and software. Bed-wetting monitoring module and music playing are added in the system. The control scheme is more scientific and reasonable, stable performance, perfect function, low cost and ideal practical effect..
